U.S. Spot Bitcoin ETFs Draw $526.7 Million, Best Day in Nearly a Month, Led Entirely by BlackRock's IBIT

U.S. spot Bitcoin ETFs took in $526.7 million on Monday, their largest single-day inflow since Sept. 22, according to Decrypt's ETF tracker. The gain snapped two weeks of selling that drained about $910 million from the funds. BlackRock's iShares Bitcoin Trust (IBIT) accounted for $665.2 million of buying, exceeding the entire net total, per Farside Investors. Fidelity's FBTC lost $83.6 million and Grayscale's GBTC shed $54.9 million, while other funds recorded no flows. Spot Ethereum ETFs lost $103 million, their fourth straight day of outflows, with BlackRock's ETHA accounting for $95.4 million of the exit. Solana ETFs lost $6.7 million. Net across Bitcoin, Ethereum and Solana funds, roughly $417 million was still drawn. Bitcoin traded near $82,000, close to the $82,300 average cost basis Nexo analyst Iliya Kalchev estimated for ETF holders. The 10-year Treasury yield held above 5% on Monday, competing with non-yielding Bitcoin. The funds remain about $88 million in the red for October, with the Federal Reserve meeting Oct. 27-28.
